Title:
GREEN-LIGHT IRIDIUM (III) COMPLEX AND PREPARATION METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/172405
Kind Code:
A1
Abstract:
Provided are a green light-iridium (III) complex and preparation method and use thereof; the structural formula of the green-light iridium (III) complex is represented as formula (I), m being 2 or 3, at least one of Ar1, Ar2, Ar3, Ar4, and Ar5 being a group having a fluorobenzene unit, the structural formula of the group being represented as formula (II), R1, R2, R3, R4, and R5 being H, CH3, F or CF3, and at least one of R1, R2, R3, R4, and R5 being F or CF3. The green-light iridium (III) complex has higher luminous efficiency, and the preparation method thereof has mild reaction conditions, and simple synthesis steps, and is easy to process; in addition, the fluorobenzene group having an electron transport performance is introduced, thus improving the transfer capacity of current carrier, promoting balanced transport of excitons, better compositing the excitons, and improving the performance of an organic light-emitting diode(OLED) device.
